SAFETY INFORMATION

EAU41467

Be a Responsible Owner

As the vehicle’s owner, you are respon­sible for the safe and proper operation
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de­pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before
riding this motorcycle.
He or she should:

● Obtain thorough instructions from

a competent source on all aspects
of motorcycle operation.

● Observe the warnings and mainte-

nance requirements in this Own­er’s Manual.

● Obtain qualified training in safe

and proper riding techniques.

● Obtain professional technical ser-

vice as indicated in this Owner’s
Manual and/or when made neces­sary by mechanical conditions.

Safe Riding

Perform the pre-operation checks each
time you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment damage. See page 5-1
for a list of pre-operation checks.

● This motorcycle is designed for off-

road use only, therefore, it is illegal
to operate it on public streets,
roads, or highways, even a dirt or
gravel one. Off-road use on public
lands may be illegal. Please check
local regulations before riding.

● This motorcycle is designed to car-

ry the operator only. No passen­gers.

● The failure of motorists to detect

and recognize motorcycles in traf­fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did
not see the motorcycle. Making

yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.

Therefore:

• Wear a brightly colored jacket.

• Use extra caution when you are

approaching and passing
through intersections, since in­tersections are the most likely
places for motorcycle accidents
to occur.

• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.

● Many accidents involve inexperi-

enced operators.

• Make sure that you are qualified
and that you only lend your mo­torcycle to other qualified opera­tors.

• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.

• We recommend that you prac­tice riding your motorcycle until
you have become thoroughly fa­miliar with the motorcycle and all
of its controls.

2

SAFETY INFORMATION

● Many accidents have been caused

by error of the motorcycle opera­tor. A typical error made by the op­erator is veering wide on a turn
due to excessive speed or under-

2

cornering (insufficient lean angle
for the speed). Never travel faster
than warranted by conditions.

● Ride cautiously in unfamiliar ar-

eas. You may encounter hidden
obstacles that could cause an ac­cident.

● The posture of the operator is im-

portant for proper control. The op­erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the motorcy­cle.

● Never ride under the influence of

alcohol or other drugs.

● Be sure the transmission is in neu-

tral before starting the engine.

Protective Apparel

The majority of fatalities from motorcy­cle accidents are the result of head in­juries. The use of a safety helmet is the
single most critical factor in the preven­tion or reduction of head injuries.

● Always wear an approved helmet.

● Wear a face shield or goggles.

Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.

● The use of a jacket, heavy boots,

trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.

● Never wear loose-fitting clothes,

otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.

● Always wear protective clothing

that covers your legs, ankles, and
feet. The engine or exhaust sys­tem become very hot during or af­ter operation and can cause burns.

2-2

Avoid Carbon Monoxide Poisoning

All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car­bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu­sion, and eventually death.
Carbon Monoxide is a colorless, odor­less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison­ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT­MENT.

● Do not run engine indoors. Even if

you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap­idly reach dangerous levels.

● Do not run engine in poorly venti-

lated or partially enclosed areas
such as barns, garages, or car­ports.

SAFETY INFORMATION

● Do not run engine outdoors where

engine exhaust can be drawn into
a building through openings such
as windows and doors.

Genuine Yamaha Accessories

Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail­able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection to
Yamaha manufacture parts and acces­sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en­dorse nor recommend the use of ac­cessories not sold by Yamaha or
modifications not specifically recom­mended by Yamaha, even if sold and
installed by a Yamaha dealer.

Aftermarket Parts, Accessories, and
Modifications

While you may find aftermarket prod­ucts similar in design and quality to
genuine Yamaha accessories, recog­nize that some aftermarket accessories
or modifications are not suitable be­cause of potential safety hazards to you
or others. Installing aftermarket prod­ucts or having other modifications per­formed to your vehicle that change any
of the vehicle’s design or operation
characteristics can put you and others
at greater risk of serious injury or death.
You are responsible for injuries related
to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.

● Never install accessories that

would impair the performance of
your motorcycle. Carefully inspect
the accessory before using it to
make sure that it does not in any
way reduce ground clearance or

2-3

cornering clearance, limit suspen­sion travel, steering travel or con­trol operation.

• Accessories fitted to the handle­bar or the front fork area can
create instability due to improper
weight distribution. If accesso­ries are added to the handlebar
or front fork area, they must be
as lightweight as possible and
should be kept to a minimum.

• Bulky or large accessories may
seriously affect the stability of
the motorcycle. Wind may at­tempt to lift the motorcycle, or
the motorcycle may become un­stable in cross winds.

• Certain accessories can dis­place the operator from his or
her normal riding position. This
improper position limits the free­dom of movement of the opera­tor and may limit control ability,
therefore, such accessories are
not recommended.

● Use caution when adding electri-

cal accessories. If electrical acces­sories exceed the capacity of the
motorcycle’s electrical system, an

2

SAFETY INFORMATION

electric failure could result, which
could cause a dangerous loss of
lights or engine power.

Aftermarket Tires and Rims

The tires and rims that came with your

2

motorcycle were designed to match the
performance capabilities and to provide
the best combination of handling, brak­ing, and comfort. Other tires, rims, siz­es, and combinations may not be
appropriate. Refer to page 7-14 for tire
specifications and more information on
replacing your tires.

Transporting the Motorcycle

Be sure to observe following instruc­tions before transporting the motorcy­cle in another vehicle.

● Remove all loose items from the

motorcycle.

● Check that the fuel cock (if

equipped) is in the “OFF” position
and that there are no fuel leaks.

● Point the front wheel straight

ahead on the trailer or in the truck
bed, and choke it in a rail to pre­vent movement.

● Shift the transmission in gear (for

models with a manual transmis­sion).

● Secure the motorcycle with tie-

downs or suitable straps that are
attached to solid parts of the mo­torcycle, such as the frame or up­per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or parts
that could break). Choose the lo­cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.

● The suspension should be com-

pressed somewhat by the tie­downs, if possible, so that the mo­torcycle will not bounce excessive­ly during transport.
